It’s no secret that Americans have gotten much, much bigger over the past few decades. The signs are all around us, from XXXL clothing sizes to supersize movie seats and even coffins.

According to the latest analysis from the Centers for Disease Control and Prevention, the average American man now stands at 5-feet-9 1/4 inches tall and weighs 196 pounds — up 15 pounds from 20 years ago. For women, the change has been even more striking: The average female today stands 5-feet-3 3/4 inches and weighs 169 pounds. In 1994, her scale read 152 pounds.

This data on the state of our weight comes from the National Health and Nutrition Examination Surveys (NHANES), a combination of interviews and physical examinations that’s considered the gold standard measurement.

Since the 1980s, the NHANES has been charting obesity rates — and extreme obesity rates — as they’ve soared. All told, according to the CDC, some 33 percent of American adults are now overweight, 38 percent are obese, and 17 percent of children and adolescents are obese. Alongside this trend, we’ve seen rising rates of associated chronic disease — like diabetes, heart disease, and metabolic syndrome.

Clearly it’s gotten easier and easier to gain weight, and harder and harder to avoid it.
